Description
In the Linux kernel, the following vulnerability has been resolved:
xfrm: Zero padding when dumping algos and encap
When copying data to user-space we should ensure that only valid
data is copied over. Padding in structures may be filled with
random (possibly sensitve) data and should never be given directly
to user-space.
This patch fixes the copying of xfrm algorithms and the encap
template in xfrm_user so that padding is zeroed.
Affected configurations
• linux linux kernel (>= 5.11 < 5.15.106)
• linux linux kernel (>= 5.16 < 6.1.23)
• linux linux kernel (>= 6.2 < 6.2.10)
• linux linux kernel 6.3
